So how do the two phones compare? Here's a TUAW exclusive iPhone-DynaTAC smackdown.
Battery Life. The iPhone is the clear winner.
Tactile dialing feedback. The DynaTAC's physical buttons nudges it into the win zone for that force feedback experience.
Portability. You can stick the iPhone in your pocket. Inserting the DynaTAC into clothing (or other areas) may cause permanent physical harm.
Expandability. Neither the iPhone nor the DynaTAC officially supports third party apps. (But you can still hack your iPhone. Just don't tell Steve Jobs.)
Muscle Development. You're not going to develop any muscle tone by lifting an iPhone.
Suitability for use as doorstop. No contest. DynaTAC for the win.
Thanks to Ashton for sending these in. I hope you enjoy looking through the pictures as much as I did.
